Genetic influences (G) significantly affect restraint (RES), internal locus for hunger (HUN), and emotional and situational susceptibility to disinhibition (DIS) with heritabilities of 52%, 50%, 55%, and 38%, respectively.
Understanding the genetic influences can help tailor interventions for eating behaviors.

However, G had a significant influence on RES, internal locus for HUN, and emotional and situational susceptibility to DIS (with heritabilities of 52%, 50%, 55% and 38%, respectively).
Why this rating
The study design involving twins allows for robust conclusions about genetic influences.

More from this paper
- The variance of most Eating Inventory (EI) variables is primarily explained by unique environmental influences (E), with E explaining 71% of the variance in external locus for hunger (HUN) and 69% in strategic dieting behavior of restraint (RES).Strong
- Disinhibition (DIS) and hunger (HUN) share a common influence, while restraint (RES) appears to be a distinct construct.Strong
